Ventilation roof

ABSTRACT

A ventilation roof contains: at least one frame and multiple stop members. The at least one frame includes at least one top sheet, at least one bottom sheet, at least one internal fence, and at least one hollow portion. The at least one top sheet has at least one air vent defined along a vertical direction, one of the at least one internal fence has an air inlet extending from a horizontal direction and communicating with the at least one air vent and the at least one hollow portion, and each of the at least one internal fence has multiple recesses. The multiple stop members are retained in the multiple recesses and are crisscross accommodated in the at least one hollow portion so that at least one zigzag channel forms in the at least one hollow portion.

FIELD OF THE INVENTION

The present invention relates to a ventilation roof which contains azigzag channel configured to flow airs effectively.

BACKGROUND OF THE INVENTION

Referring to FIG. 1, a conventional ventilation roof contains twoopposite frames 9 (one of the two opposite frames is shown) and matewith a covering plate 910 so that air flows outside and inside abuilding, wherein a zigzag channel is defined among each of the twoopposite frames 9 and multiple stop members 90.

Each frame 9 includes a top sheet 91, a bottom sheet 92, an internalfence 93, and a hollow portion 94 surrounded by the top sheet 91, thebottom sheet 92, and the internal sheet 93. The internal sheet 93 has anair inlet 931 extending from a horizontal direction X, and the bottomsheet 92 has an air vent 921 defined along the horizontal direction X,wherein the air inlet 931 is higher than the air vent 921, and the airvent 921 and the air inlet 931 communicate with the hollow portion 94.The internal fence 93 has multiple recesses 932 configured to retainwith each of the multiple stop plates 90, and the multiple stop members90 are crisscross arranged downward so that the zigzag channel forms inthe hollow portion 94, and hot air flow discharges out of the air inlet931 along the zigzag channel.

Although the zigzag channel is defined by the air inlet 931, the airvent 921, and the multiple stop members 90, a back pressure of a windresistance produces because the air vent 921 is defined along thehorizontal direction X, thus lowering air ventilation as discharging thehot air flow.

The present invention has arisen to mitigate and/or obviate theafore-described disadvantages.

SUMMARY OF THE INVENTION

The primary aspect of the present invention is to provide a ventilationroof which discharges hot air flow effectively and reduces a backpressure.

To obtain above-mentioned aspects, a ventilation roof provided by thepresent invention comprises: at least one frame and multiple stopmembers.

The at least one frame includes at least one top sheet, at least onebottom sheet, at least one internal fence, and at least one hollowportion surrounded by the at least one top sheet, the at least onebottom sheet, and the at least one internal fence. The at least one topsheet has at least one air vent defined along a vertical direction, theat least one internal fence has at least one air inlet extending from ahorizontal direction and communicating with the at least one air ventand the at least one hollow portion, and each of the at least oneinternal fence has multiple recesses.

The multiple stop members are retained in the multiple recesses and arecrisscross accommodated in the at least one hollow portion so that atleast one zigzag channel forms in the at least one hollow portion.

The at least one air vent of the present invention is defined along thevertical direction, so the hot air flow discharges out of the buildingeasily by using a pressure drop of the exterior wind, when guiding thehot air flow in the building.

The hot air flow flows upward along the zigzag channel and dischargesout of the air vent in the vertical direction so as to overcome the windresistance. Furthermore, the rainwaters do not flow into the buildingfrom the air vent by way of the at least one stop member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 2 and 3, a ventilation roof 100 according to apreferred embodiment of the present invention is mounted on an opening110 of a corrugated roofing sheet 100 of a building and mates with acovering plate 200 (such as made of tempered glass) so as to obtainbright lights and heat dissipation. In this embodiment, the ventilationroof 100 comprises two opposite frames 1 symmetrically arranged and twostop members 2 accommodated in each of the two opposite frames 1.

Each of the two opposite frames 1 includes a hollow body, a crosssection of which is in a rectangle shape, a top sheet 11, a bottom sheet12, an internal fence 13, and a hollow portion 14 surrounded by the topsheet 11, the bottom sheet 12, and the internal fence 13.

The top sheet 11 has an air vent 111 defined along a vertical directionY and communicating with the hollow portion 14, and the air vent 111 hasa mesh layer formed on a top thereof.

The bottom sheet 12 has a water outlet 121 in communication with thehollow portion 14.

The internal fence 13 of each frame 1 has an air inlet 131 extending ona side thereof from a horizontal direction X, and the internal fence 13has multiple recesses 132 defined thereon, wherein the air vent 111 andthe air inlet 131 communicate with the hollow portion 14, and the recess132 is configured to retain each of the two stop members 2.

Each stop member 2 is retained ion the recess 132, and the two stopmembers are crisscross accommodated in the hollow portion 14 so that azigzag channel (denoted by an arrow in FIG. 3) forms in the hollowportion 14.

Each stop member 2 includes a first segment 21 retained in the recess132, a second segment 22 opposite to the first segment 21, and multipledrainage holes 23 defined between the first segment 21 and the secondsegment 22. In this embodiment, the two stop members 2 are obliquely andoppositely fixed in the hollow portion 14 and tilt upward along thehorizontal direction X, wherein a tilted angle of each stop member 2 isless than 45 degrees. A distal portion 221 of the second segment 22extends upward along the vertical direction Y, and two second segments22 of the two stop members 2 are crisscross arranged so as to postponeairs and rainwaters to flow into the building from the air vent 111 andto avoid the rainwaters rushing back to the building from the hollowportion 14 via the air inlet 131. Each stop member 2 is obliquely fixedin the hollow portion 14 so as to avoid the rainwaters gathering in thebuilding by way of the multiple drainage holes 23.

In this embodiment, one of the two stop members 2 proximate to the airinlet 131 is located on the side of the internal fence 13 on which theair inlet 131 is defined, the one stop member 2 is located above the airinlet 131, and the zigzag channel is a flowing path in which the airsflow along the air inlet 131, the two stop members 2, and the air vent111.

In assembly, hot air flow in the building flows upward via the opening110 and enters into the zigzag channel via the air inlet 131, thereafterthe hot air flow discharges out of the air vent 111 along the zigzagchannel. The air vent 111 is defined along the vertical direction Y, soa low pressure portion of exterior wind produces in the air vent 111 anddoes not stop the air vent 111 when the wind flows, thus dissipating thehot air flow out of the building.

The conventional ventilation roof contains the channel downwardextending to the air vent so that the hot air flow discharges upward,thus causing wind resistance to reduce air ventilation.

The air vent 111 of the present invention is defined along the verticaldirection Y, so the hot air flow discharges out of the building easilyby using a pressure drop of the exterior wind, when guiding the hot airflow in the building.

The hot air flow flows upward along the zigzag channel and dischargesout of the air vent in the vertical direction so as to overcome the windresistance. Furthermore, the rainwaters do not flow into the buildingfrom the air vent 111 by way of the two stop members 2.
